Wheel set with a decorative lamp structure

ABSTRACT

A wheel set with a decorative lamp structure includes a main wheel and a pair of auxiliary wheels. The auxiliary wheels are provided at respective sides of the main wheel. The main wheel comprises circular troughs at two outer sides having a smaller diameter than that of the center of the main wheel. The circular troughs are to accommodate decorative lamps and covers. When the wheel set moves forward, the main wheel sparkles light and the decorative lamps and the covers are not in contact with the ground to avoid from damage.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a wheel set with a decorative lamp structure, and more particularly to a main wheel provided with decorative lamps and covers at two outer sides having a smaller diameter. When the wheel set rolls, the decorative lamps and the covers will be protected from touching the ground directly.

2. Description of the Prior Art

A conventional egg-shaped wheel set applied to a playing cart includes a main wheel and two auxiliary wheels. By rolling the wheel set, the playing cart is pushed forward. This design has only one function as to push the cart forward, which is tedious to kids after a certain period of time.

A later design was introduced to the market, which is provided with decorative lamps on the wheel to increase attraction, but they are so fragile and easy to be damaged.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a wheel set with a decorative lamp structure, which comprises a main wheel and a pair of auxiliary wheels. The auxiliary wheels are provided at respective sides of the main wheel. The main wheel comprises circular troughs at two outer sides having a smaller diameter to accommodate decorative lamps and covers.

Each auxiliary wheel comprises a recess to accommodate a battery or a generator.

The present invention has the following advantages:

-   1. The decorative lamps and the covers in the circular troughs of     the main wheel are not in contact with the ground and will not be     damaged. -   2. The auxiliary wheel is provided with a battery or a generator to     self-support electricity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIGS. 1 and 2, a preferred embodiment of the present invention comprises a main wheel 1 and two auxiliary wheels 2. The auxiliary wheels 2 are provided at respective sides of the main wheel 1.

The main wheel 1 includes circular troughs 11, decorative lamps 12 and covers 13. The circular troughs 11 are disposed at two outer sides having a smaller diameter to accommodate the decorative lamps 12 and the covers 13. Each auxiliary wheel 2 has a recess 21 to accommodate a battery 22 or a generator 23.

As shown in FIG. 2, when the preferred embodiment of the present invention moves forward, the auxiliary wheels 2 will roll on the ground to activate the generator 23 to generate electricity to supply the decorative lamps 12 in the circular troughs 11. The light shines through the covers 13 to provide an attractive effect. The circular troughs 11, the decorative lamps 12 and the covers 13 are disposed at the two sides having a smaller diameter, which keeps them away from the ground.
